SWATHING ATTACHMENT FOR HARVES'TERS,

SPECIFICATION forming' part of Letters Patent No. 251,845, dated January3, 1882;

Application filed August 20, 1881. (No model.) I

To all whom it may concern:

Be itfknown that \ve,,OHARLEs G. DUNKEL and ALBERT TSGHOP, ofHarrisburg, county of Dauphin, State of Pennsylvania, have inv ventednewand useful Improvementsin Swathing Attachments to Harvesters, ofwhich the following is a full and exact description, reference being hadto the accompanying drawings, in which- IO Figure 1 is a perspectiveview of a harvesting-machine, or of so much thereof as is necessary toshow our improvement applied; and l i g. 2 is a rear elevation of thesame.

Our invention relates to a device adapted to be applied to a harvesterfor discharging the grain therefrom in a continuous swathbehind themachine, in lieu of the usual appliances forbinding the grain by hand orautomatically,

and is designed for use as a'substitute for such hand or automaticbinding attachments where j the nature or condition of the crop rendersit desirable to leave the grain or other cropsuch as oats orflax-unbound and upon the ground for curing or other purpose; and tothis end theinvention consists in the employment of a spiraldelivery-chute adapted to receive the grain from the grain -dischargingmechanism, and to deliver the same in a con tinuous swath upon theground, out of the path ofthe team upon the succeeding round, and? withthe stalks lying at right angles to the path of the machine, and theline of the swath similar to the swath in which it is deposited when outby hand with a cradle, as will be explained.

- In the accompanying drawings, Arepresen ts the main frame of themachine, made in any usual or suitable form, and to which the plat formand elevator-frames are applied, provided with platform and elevatorrakes or aprons, all of said parts being also of any usual or preferredconstruction and arrangement.

B B represent the elevator-frame, supporting the rollers of the apronsor other mechanism for elevating the grain over the driving-wheel O, fordischarging it upon the opposite side of the wheel to that upon which itis cut. D is a" longitudinal bar or frame-piece extending betweenthefront and rear upright portions of the frame B, just under the upperroller, E, of

the lower elevator-apron, where two are used,

or in such relation to the discharging end of the elevator that thegrain'will pass above and over and be discharged outside of said bar,which, in the construction shown, forms the support fora spiral chute-orswathing device, F.' This swathin g device is represented in thedrawings as made of sheet metal, and in asingle piece, extending fromthe board or bar D, to which its upper end or edge lyingin aplane, 6cparallel with the outer vertical face of said bar, or nearly so, issecured, downward, and on its forward edge outward and rearward in acurved line, giving it a quarter-turn, or thereabout, in spiral form, insuch manner as to bring its lower 6 discharging end into a horizontal ornearlyhorizontal position, and at right angles, or nearly so, to itsupper end and to the path of the machine.

The above description is approximate only, 7c as it will be evident thatthe butts of the grain, being in advance and having farther to travel inbeing turned upon the head as a center, will necessarily have to travelfaster, and consequently will be thrown farther from thelower 7 5 end ofthe chute than theheads, and the lower end oftthe chute. will thereforebe shortened toward its outer side or edge, making the spiral somewhatless than a quarter of a circle.

The rearinner edge of the chute has a backward inclination, and bypreference a slight concavity is given to the upper face of the chute insuch manner that the straw will rest mainly on its ends upon the chute,as by this means the light and bearded heads will serve to slightlyretard the progress of the straw at thatend, while the smoother andheavier butts will slide quickly and easily down the outer edge of thechute, facilitating the turning of the straw from a position parallelwith the path l of the machine to one at right angles thereto,

or thereabout, in which it is deposited, with the straw lying crosswiseof the line of the swath. By this arrangement, when, for any reason, itis desired to leave the crop upon the 5 ground, it can be done by simplyremoving the hand or automatic binder appliances and substitutingtherefor the chute or swathing device described, and by means of whichthe grain will be deposited in suitable form for cur-- 1o ing, ifneeded, as well as in convenient shape for taking it up when desired.

We have described the chute as made of sheet metal and in a single pieceor width; but it will be apparent that other materials may be employedin its construction, and that it'is not necessary that it should be inone piece or width so long as the device, as a whole, hasa spiral orequivalent form given to its upper surface for turning the straw, andsaid surface is adapted to permit the straw or grain to slide freelyover it in its descent to the ground.

Having now described our invention, we claim as new- 1. In aharvesting-machine, a spiral chute or swathing device located on thestubble side of the main frame and outside of the drivewheel.

2. Thecombinatiomin aharvesting-machine, of mechanism for elevating thegrain over the main drivewheel and a swat'hing device for receiving thegrain from said elevating mechanism and depositing it upon theground inacontinuousswath, with the stalks at right angles, or thereabout, to theline of said swath.

3. The combination, in aharvesting-machine, of a carrying-platform, aswathing device for depositing the grain in a continuous swath upon theground, a driving-wheel interposed between said platform and swathingdevice, andmechanism for elevating the grain over the driving-wheel anddelivering it to said swathing device.

4. In a harvesting-machine, the combination of mechanism for elevatingthe grain and a swathing device adapted to receive the grain from saidelevating mechanism, and to deposit the same upon the ground, with thestraw at right angles, or nearly so, to the position inwhich it wasreceived from the elevating mechanism.
